^That's an interesting find.
On another note, I found some Real3D PRO-1000 demos but they are not from an actual Model 3 board and have nothing to do with SEGA. They're running on a PRO-1000 image generator which I guess means a single GPU (?) and Model 3 had 2 of them.

Playable space shooter and non-playable car demos, starting @ 5:37:
Note that right after those demos, the video cuts to footage of a
Virtua Fighter 3 arcade machine.
